Analyzes code files and reports statistics including line counts, file counts by extension, and total size.
4 of 22 test cases passed with the skill.
Tokens, turns and time describe resource use, not a dollar price.
Lift withheld: 4 comparable cases; this report requires 8.
This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
A test case the skill fixed. Same model, same prompt, with and without the skill.
Analyze a repository containing 8 distinct file extensions (.js, .css, .html, .ts, .json, .md, .py, .sh) and produce the top file extension summary.
| Checked | Without skill | With skill |
|---|---|---|
| Limits the top file extensions list to at most 5 extension entries. | Missed | Passed |
The instructions your model reads when the skill loads.
Analyzes code files and generates statistics about a codebase.
When invoked, this skill will:
node_modules/, .git/, dist/, and build/ unless the user explicitly asks to count them. These are dependencies, repository metadata, or generated output rather than project source.Always use this exact format for the output:
# Code Statistics
## Summary
- Total Files: <count>
- Total Lines: <count>
- Total Size: <size_bytes> bytes
## Files by Extension
| Extension | Files | Lines |
|-----------|-------|-------|
| .go | 12 | 1500 |
| .md | 5 | 200 |
## Top 5 File Extensions by Line Count
1. .go — 1500 lines
2. .md — 200 lines
## Largest Files (top 5)
1. main.go (500 lines)
2. util.go (300 lines)
